In this research, researcher will examined the theoretical background of open education. Based on the result of the development of the suggested guidelines for a home economics teaching/learning program, researcher concludes that in order for the teaching/learning programs based on open education to be efficiently acieved in the classroom environment-organization at the middle school the following reform measures must accompany these programs. First, in order for the special characteristics of open education, i.e., individualized and small group study, to be effectively achieved, it is necessary to improve the physical classroom environment-organization. Second, the two class hours per week currently allotted for home economics are not sufficient to convey the information in the textbook. In order to reach objectives of teaching home economics according to open education a guarantee of a few more class hours is demanded. Third, in order to successfully achieve teaching/learning programs following open education, it is necessary for home economics teachers to make efforts to develop educational materials, and to engage in ongoing research and inservice training. For this to occur, measures must be taken to reduce the workload of teachers.

Considerations of how to facilitate aging-in-place(AIP) are becoming increasingly pertinent as care-givers are overwhelmed by an aging population. Aging friendly home-care services combined with IT can satisfy the needs of the elderly suffer from chronic diseases such as depression and dementia. Therefore, we propose future smart phone services and application technologies which can estimate emotional states of the aged and respond to the desire to be happy with mental health, connectedness and consolation from peoples. Firstly, we introduce depression measurement techniques to estimate the severity of depression using multiple sensors. At second, the emotional responding services are categorized to four parts and the details are described. Lastly, we propose the process to implement emotional communication and the application techniques(services) to fulfill the emotional satisfaction and mental healthcare for AIP using smart phone as a mediator.

SMART home is one of the most popular applications of Internet-of-Things (IoT) technologies, which is expanding in terms of range of applications. SMART home technology provides convenience at home by connecting household appliances to a single network, control, and management. However, many general home appliances do not support the network functions yet; hence, enjoying such convenient technology could be difficult, and it could be expensive in the beginning to build the framework. In addition, even though products with SMART home technologies are purchased, the control systems could differ from device to device. Thus, in this paper, we propose a SMART home framework, called an S-mote that can operate all the IoT functions in a single application by adding an infrared or radio frequency module to general home appliances. The proposed framework is analyzed using four types of performance tests by five evaluators. The results of the experiment show that the SMART home environment was implemented successfully and that it functions appropriately, without any operational issues, with various home appliances, including the latest IoT devices, and even those equipped with an infrared or radio frequency module.

Objectives: The purpose of the study was to develop dietary change program items that could be used to improve dietary life of the elderly and investigate their validity. Methods: The survey was were analyzed by SPSS program (Ver. 21) and descriptive statistics was performed; a t-test, ${\chi}^2$ test, One-way ANOVA and Friedman test were used to determine the priority. Results: Programs for feeding senior citizens that need to be newly established are largely divided into two fields, namely, application of welfare facilities and application of home care, classified into large, medium and sub-classes. The large class was divided into nutrition management, sanitary control, and other health management. The medium class of nutrition management was divided into nutrition education, nutrition intervention, and menu management and supply. The sub-class was composed of division into application of welfare facilities for the elderly and application of home care for the same age group. Responses showed high rate saying that all the categorized items were necessary and valid. With respect to expectation effect on a community program for old people feeding, 'yes' was 65 people (55.6%) showing very high expectation toward the question whether a community program for old people feeding are newly set up. Conclusions: It is believed that nutrition for the aged will be improved and it will be a help not only to a small facilities without obligation of employing a dietician but also to the aged at home if a community program for old people feeding are newly established.

This study providesd an empirical analysis of trip-chaining behavior and its application to transportation planning. In the empirical analysis, changes in trip-chaining patterns since 1970 have been examined and details of current trip-chaining behavior as they describe shopping trip-chaining behavior has changed. Individual trip-chaining has become longer and complex. It appears that the average number of trips per chains has substantially increased over the past 20 years. An increased number of trips in chains means fewer home-based trips. Changes in trip-chaining behavior have several consequences. Important consequences are for transportation and land-use planning. Up to now trips have been treated as if they are independent clusters of home-to-destination-to-home; this approach has not usually taken into account the trip-chaining behavior of individuals. this calls for a different approach to at least the trip generation and trip distribution part of transportation planning. In this study, application of trip-chaining behavior to trip distribution model formulation is proposed and its calibration results are presented.
